Subject: sandbox: don't call os_close with invalid file descriptor
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-logo.png?a=commitdiff_plain;h=2c3fa4b8add3cb6a440184ab67debc6867d383c0;p=u-boot.git

sandbox: don't call os_close with invalid file descriptor

If open() fails it returns -1. Calling close() with this value
makes no sense. Return -EIO instead.
